(Wednesday, June 11, 2008 - 17:25 EDT)The lens we review today is tiny - so tiny in fact, that it ran the risk of getting lost in the sofa cushions. Fortunately we kept it under tight surveillance and put it through its paces in our test lab: today's lens, the Olympus 25mm f/2.8 Zuiko Digital.The Olympus 25mm f/2.8 Zuiko Digital is a fixed-focal length "pancake" lens, and probably the smallest that Olympus produces. A pancake lens is typically constructed with the fewest number of lens elements possible, and in this case the 25mm is no exception, with just 5 lens elements in four groups.
